Veena Basavaraj commented on SQOOP-1168:
----------------------------------------

[~gwenshap] I might just implement it and send it, since I did highlight that 
the way to do this is to put a value in the context objects. One way is to use 
a standardized KEY (CONNECTOR_OUPUT_  so we know that if that key exists then 
it has the output that I want to store on the repo, as simple as that, there is 
nothing more to it.

My goal is not to introduce anything specific to delta or incremental, later on 
this should extend to write any other info from connector to repository via 
sqoop. There is nothing special about last value or rows read or any other 
foobar

hope this makes sense. This was explained in the design wiki already
